  Below, one Embodiment of the cutting device of the resin molded product by this invention is described with reference to FIGS. 1-5.

  The cutting device 1 according to the present embodiment cuts out the outer shape of a resin molded product (a foam for food made from foamed resin) W thermoformed from the foamed resin sheet S into a strip-like foamed resin sheet S in the form of an upwardly projecting wedge. belongs to. A plurality of resin molded products W are thermoformed at intervals in the longitudinal direction on the foamed resin sheet S, and the foamed resin sheet S is in a substantially horizontal posture with the bottom side of the resin molded product W facing upward. In the figure, it is carried from the right to the left.

  As shown in FIG. 1, the cutting apparatus 1 includes an upper die 10 driven vertically by a ram of a press machine (not shown) and a lower die 12 fixed on a bolster 3 of the press machine. Have.

  A cylindrical flat mounting member 16 is fixed to the lower surface of the upper mold 10 by a plurality of bolts 14. An annular flat plate member (blade receiving member) 22 is fixed to an annular lower end surface 16A of the flat plate mounting member 16. The flat plate member 22 is made of a resin such as polypropylene (PP) or a metal such as stainless steel, and includes a flat annular surface 22A opposed to the outer portion (peripheral portion) of the resin molded product W.

  Inside the flat plate mounting member 16, a pressing member 24 is disposed movably in the vertical direction. The pressing member 24 is constituted by a cylindrical member 26 having an outer peripheral surface 26A slidably contacting the inner peripheral surface 16B of the flat plate mounting member 16, and an end plate member 30 fixed to the upper end of the cylindrical member 26 by a bolt 28. It is done. The cylindrical member 26 has an outer annular portion 26B at its lower end that abuts on the back surface of the annular outer peripheral portion (flanged portion) Wa of the resin molded product W. An inner peripheral surface 26C on the lower end side of the cylindrical member 26 is shaped to conform to the outer peripheral shape of the resin molded product W.

  The lower end of a cylindrical post member 32 is fixed to the central portion of the end plate member 30. The post member 32 extends vertically above the upper mold 10 through the through hole 34 formed in the upper mold 10 from the end plate member 30. A cap member 36 is fixed to the upper end of the post member 32. A compression spring 38 is mounted between the cap member 36 and the upper mold 10 by a compression coil spring. The pressing spring 38 biases the pressing member 24 upward with respect to the upper die 10. As a result, as shown in FIG. 1, in the free state, the pressing member 24 is at the upper limit highest position with respect to the upper die 10 by the spring force of the pressing spring 38.

  A shock absorbing member 40 by a rubber O-ring is attached to the upper surface of the end plate member 30. The shock absorbing member 40 mitigates the impact when the upper surface of the end plate member 30 abuts on the lower surface of the upper die 10 by the spring force of the pressing spring 38, and the generation of an impact noise is suppressed.

  The pressing member 24 abuts on the outer peripheral portion Wa of the resin molded product W with the outer annular portion 26B when the upper die 10 descends to the bottom dead center or the vicinity thereof and the inner peripheral surface 26C of the cylindrical member 26 is a resin molded product It abuts on the outer circumferential surface Wb of W (see FIG. 3). Furthermore, the pushing member 24 is lowered and moved relative to the upper die 10 against the spring force of the pushing spring 38 by the cap member 36 being pushed downward by an independent driving device (not shown).

  A plurality of hanger rods 42 are screwed to the end plate member 30 by screw portions 42A. Each hanger rod 42 is suspended from the end plate member 30 and disposed inside the tubular member 26. Each hanger rod 42 suspends and supports one annular shaped knockout member 44. The suspension support of the knockout member 44 is achieved by the shaft portion 42B of each hanger rod 42 penetrating through the plurality of insertion holes 44A formed in the knockout member 44, and the diameter-expanding hole 44B and the insertion holes 44A formed in the knockout member 44. The pushing member 24 of the knockout member 44 is brought into contact with the shoulder portion due to the inner diameter difference between the enlarged diameter head 42C formed on the tip (lower end) of the shaft portion 42B and the shoulder portion due to the outer diameter difference. In the state where the lower limit position (the lowest position) is set, the knockout member 44 is moved in the predetermined range relative to the pushing member 24 and the upper die 10 in the vertical direction.

  The knockout member 44 is movable within a predetermined range in the vertical direction with respect to the pushing member 24 by the hanger rod 42, and as shown in FIG. 1 when the upper die 10 is in the raised position (top dead center). It is located at the lowest position by its own weight.

  Between the knockout member 44 and the end plate member 30, a knockout spring 46 by a compression coil spring is provided. The knockout spring 46 is provided for each hanger rod 42 and biases the knockout member 44 in the lowering direction with respect to the pushing member 24. That is, the knockout member 44 is further floatingly supported from the pressing member 24 under downward spring biasing by the knockout spring 46, and in the free state, is at the lowermost lowered position relative to the pressing member 24. .

  The knockout member 44 is formed in an annular shape, and includes an annular lower surface 44C that can contact the bottom surface Wc of the resin molded product W from the upper side. The lower surface 44C is set to abut on the bottom surface Wc of the resin molded product W while the upper mold 10 is being lowered (see FIG. 2).

  The lower surface 44C of the knockout member 44 abuts on the bottom surface Wc of the resin molded product W during the descent of the upper die 10, so that the weight of the knockout member 44 and the spring 46 for knockout are further lowered to the bottom dead center of the upper die 10. Against the spring force, in other words, while moving the knockout spring 46 upward, it moves upward relative to the pressing member 24 and the upper die 10, and the resin molded product W is moved by the resilient force of the knockout spring 46. It is biased toward the passage space 54 of the blade member 50 described later.

  A cylindrical blade member 50 is fixed to the upper surface of the lower die 12 by a plurality of bolts 48. The cutter member 50 includes an upper edge forming a pressing / cutting blade 52 called a Thomson blade for cutting out the outer shape of the resin molded product W by pressing the outer peripheral portion Wa of the resin molded product W against the annular surface 22A of the flat plate member 22 The inside of 52 defines a passage space 54 through which the resin product W of the cutout completion passes. The passage space 54 is an opening which penetrates the cutter member 50 in the vertical direction.

  The upper mold 10 has the resin molded product W between the pressing member 24 and the cutter member 50 between the cutting position where the pressing and cutting blade 52 abuts on the annular surface 22A (see FIG. 4) and the pressing and cutting blade 52 separates from the annular surface 22A. It is movable in the up-and-down direction that is abutted against the lower die 12 between a rising position (see FIG. 1) that defines a space into which the molded foamed resin sheet S can be carried. In the position, it is vertically movable relative to the upper mold 10 within a predetermined range including at least a position abutted on the resin molded product W and a position lower than the position.

  The lower die 12 is formed with an accumulation opening 56 having an upper end communicating with the passage space 54. The accumulation opening 56 is a space for accumulating the resin molded products W from the passage space 54 in a state of being vertically laminated.

  A cylindrical suction plate 60 is attached to the inner circumferential surface of the lower mold 12 defining the accumulation opening 56. The cylindrical suction plate 60 is formed through a plurality of air suction holes 58 opened toward the accumulation opening 56. An annular air passage 62 is formed in the mounting portion of the suction plate 60 of the lower mold 12. The air passage 62 is connected to the air suction device 68 by an air passage 64 and an air pipe 66 formed in the lower mold 12. Thus, the air suction hole 58 sucks air from the accumulation opening 56 on the inner circumferential surface defining the accumulation opening 56.

  Next, the operation of the cutting device 1 having the above-described configuration will be described.

  FIG. 1 shows an initial state (starting state) in which the resin molded product W which is not punched from the foamed resin sheet S with the upper mold 10 at the top dead center (raising position) is conveyed to the cutting position by the cutting device 1. It shows. In this initial state, the pushing member 24 is at the highest position, and the knockout member 44 is at the lowest position. Conveying of the resin molded product W to the foamed resin sheet S is carried out by being supported and guided by a guide member (not shown) and substantially horizontal feeding at the illustrated height.

When the upper die 10 is lowered by the ram (not shown) from this initial state, as shown in FIG. 2, it is in the middle of lowering, that is, before the upper die 10 is located at the cutting position (bottom dead center) First, the lower surface of the knockout member 44 abuts on the bottom surface Wc of the resin molded product W located immediately below the knockout member 44.
Then, when the upper die 10 further descends toward the bottom dead center, the knockout spring 46 is flexed (compressive deformation) with the progress of the lowering, and the lower surface of the knockout member 44 is deformed by the spring force of the knockout spring 46. It is pressed against the bottom surface Wc of the resin molded product W.

  As shown in FIG. 3, when the upper die 10 is lowered close to the bottom dead center, the outer annular portion 26B of the pushing member 24 abuts on the outer peripheral part Wa of the resin molded product W from the upper side and the inner periphery of the pushing member 24. The surface 26C abuts on the outer peripheral surface Wb of the resin molded product W. At this time, the annular surface 22A of the flat plate member 22 abuts on the outer peripheral part Wa of the resin molded product W outside the outer annular part 26B, and the outer peripheral part Wa of the resin molded product W The tip end abuts from the lower side, and cutout of the outer shape of the push-cut resin molded product W by the flat plate member 22 and the push-cutting blade 52 is started.

  As shown in FIG. 4, when the upper die 10 is located at a cutting position (bottom dead center) where the press-cutting blade 52 abuts on the annular surface 22A, the cutout of the outer shape of the resin molded product W is completed. When the cutout is completed, the knockout member 44 is immediately lowered to the original lowermost position with respect to the upper mold 10 and the pushing member 24 by the self weight and the resilient force of the knockout spring 46. Thereby, the resin molded product W which has been completely cut off is separated (separated) from the foamed resin sheet S and pushed downward, that is, into the passage space 54.

  The operation of the knockout member 44 separating the resin molded product W after completion of the cutout from the foamed resin sheet S is necessarily performed by the weight of the knockout member 44 and the elastic force of the knockout spring 46 when the cutout is completed. Therefore, there is no need to externally control the operation of the knockout member 44 in synchronization with the drive timing of the upper die 10 by the press machine. Thereby, the synchronous operation of the knockout member 44 does not disturb the speeding up of the operating speed of the cutting device 1, and the speeding-up of the cutting process of the cutting device 1 can be further speeded up.

  Thereafter, the cap member 36 and the post member 34 are pushed downward by an independent drive (not shown), so that the pushing member 24 resists the spring force of the pushing spring 38 as shown in FIG. And move downward relative to the upper die 10. As a result, the resin molded product W which has been completely cut out is pushed into the passage space 54 to a position where it is stacked on the resin molded product W which has been cut out once. In this manner, the resin molded products W whose cutting is completed are accumulated in the vertical direction sequentially in the passage space 54 and the accumulation opening 56 below the passage space 54. Thereby, a large number of resin molded articles W can be accumulated in the cutting device 1.

  Since the pressing member 24 presses the annular outer peripheral portion Wa of the resin molded product W with the outer annular portion 26B, no trouble such as tilting of the resin molded product W occurs in the process of pushing the resin molded product W into the passage space 54. The lamination of the resin molded product W is favorably performed.

  The pressing member 24 does not remove the resin molded product W which has been completely cut out from the foamed resin sheet S, and the resin molded product W which has been completely removed does not interfere with the next process. Since it is only necessary to perform the pressing operation, the drive timing of the pressing member 24 does not have to be strictly synchronized with the fact that the upper die 10 is located at the bottom dead center, and the driving of the pressing member 24 is for the upper die 10 at the bottom dead center It may be started within a predetermined time after being located at. Therefore, the operation of the pushing member 24 does not inhibit the speeding up of the operating speed of the cutting device 1.

  Thereafter, the upper die 10 is returned to the top dead center by a press machine, and the pressing of the cap member 36 and the post member 34 by the driving device (not shown) is released in the rising process of the upper die 10. The spring force of the spring 38 returns to the original maximum position.

  Since the air suction hole 58 sucks the air of the accumulation opening 56 on the inner circumferential surface which defines the accumulation opening 56, dust such as swarf and the like generated by cutting out air during the accumulation process of the resin molded product W described above The resin molded product W is cleaned by being sucked into the air passage 62 from the hole 58.

  As described above, since the resin molded product W is cleaned before being taken out of the lower mold 12 and the blade member 50 in the accumulation process, there is no need to provide a cleaning process as a post process, and swarf etc. Dust does not scatter outside the cutting device 1.

  While the present invention has been described above with reference to the preferred embodiments, it is to be understood that the present invention is not limited by such embodiments as can be readily understood by those skilled in the art, and deviates from the spirit of the present invention. It can change suitably in the range which is not.

  For example, the knockout spring 46 is not essential, and as shown in FIG. 6, the knockout member 44 has its own weight when the knockout spring 46 is omitted and the upper mold 10 is in the raised position, that is, in the free state. It may be located at the lowest position only.

  Further, the pressing member 24 is not essential, and the resin molded product W has a small vertical dimension such as a dish-like one, and the knockout member 44 lowers the resin molded product W into the passage space 54 to a position not obstructing the next process. If possible, the pushing member 24 may be omitted, and the knockout member 44 may be suspended and supported directly from the upper die 10. In this case, the knockout spring 46 is provided between the upper die 10 and the knockout member 44. The cutting device 1 may have a multiple connection structure and simultaneously cut a plurality of resin molded products W. The upper die 10 may be fixed, and the lower die 12 may move in the vertical direction with respect to the upper die 10.

  Moreover, all the components shown in the above embodiment are not necessarily essential, and it is possible to select them as appropriate without departing from the spirit of the present invention.
